The U.N. Intergovernmental Panel on Climate Change (IPCC) has published an exhaustive report on the agricultural and dietary changes that will be needed to mitigate climate change. Here is a (lengthy) summary of its findings: https://www.ipcc.ch/srccl/chapter/summary-for-policymakers/
Excerpted from the IPCC's recommended food system changes:
"B.6.2
Diversification in the food system (e.g., implementation of integrated production systems, broad-based genetic resources, and diets) can reduce risks from climate change (medium confidence). Balanced diets, featuring plant-based foods, such as those based on coarse grains, legumes, fruits and vegetables, nuts and seeds, and animal-sourced food produced in resilient, sustainable and low-GHG emission systems, present major opportunities for adaptation and mitigation while generating significant co-benefits in terms of human health (high confidence). By 2050, dietary changes could free several million km2 (medium confidence) of land and provide a technical mitigation potential of 0.7 to 8.0 GtCO2eq yr-1, relative to business as usual projections (high confidence). "
The IPCC seems to be saying:
1. Whole food plant-based diets inherently serve to mitigate climate change.
2. Animal agriculture must radically change in order for the world to mitigate climate change.
